Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil-water separation technology, and in particular to an oil-water separation device for catering waste. Background Technology
[0002] Food waste refers to food scraps generated during household, catering, and food processing, including organic matter such as fruit peels, vegetables, and meat. Its high water content, easy perishability, and susceptibility to pathogens present challenges for its treatment. However, through technologies such as anaerobic fermentation, it can be transformed into bioenergy, organic fertilizer, or animal feed, achieving resource utilization. Scientific sorting and professional collection are crucial; direct landfilling or incineration must be avoided to reduce environmental pollution.
[0003] Existing methods for separating oil and water in food waste often encounter problems during the oil retrieval process. External environmental factors, such as stirring by operators, can cause the oil and water to remix, hindering complete oil separation. To overcome these drawbacks, this invention provides an oil-water separation device for food waste. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oil-water separation device for food waste.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an oil-water separation device for catering waste, comprising a separation tank, a first rotating seat fixedly connected to one side of the separation tank, an oil- and water-repellent cloth provided on the rotating shaft of the first rotating seat, a first power component provided on one side of the first rotating seat, support plates fixedly connected to both sides of the separation tank, a first gantry frame fixedly connected to the top of the support plates, a pressure wire component provided at the top of the first gantry frame, a second gantry frame fixedly connected to the top of the support plates and located on one side of the first gantry frame, a scraping component provided at the bottom of the second gantry frame, a second rotating seat fixedly connected to one side of the separation tank, a pull rope provided on the rotating shaft of the second rotating seat, a second power component provided on one side of the second rotating seat, a second roller fixedly connected to one side inside the separation tank, and one end of the pull rope and one end of the oil- and water-repellent cloth fixedly connected.
[0006] Furthermore, the first power assembly includes a first servo motor fixedly connected to one side of the first rotating seat, and the output end of the first servo motor passes through the first rotating seat and is fixedly connected to the rotating shaft inside the first rotating seat.
[0007] Furthermore, the pressing assembly includes an electric push rod fixedly connected to the top of the first gantry frame, and the output end of the electric push rod passes through the first gantry frame and is fixedly connected to a first roller.
[0008] Furthermore, the scraping assembly includes several limiting telescopic rods fixedly connected to the bottom end of the second gantry frame, a spring fixedly connected to the bottom end of the second gantry frame and around the limiting telescopic rods, a second scraper fixedly connected to the output end of the limiting telescopic rods, and a first scraper fixedly connected to the top end of the separation pool and below the second scraper.
[0009] Furthermore, the second power assembly includes a second servo motor fixedly connected to one side of the second rotating seat, and the output end of the second servo motor is fixedly connected through the rotating shaft inside the second rotating seat.
[0010] Furthermore, a PLC controller is fixedly connected to one side of the first gantry frame, and a control panel is fixedly connected to the first gantry frame below the PLC controller. The control panel and the PLC controller are electrically connected.
[0011] The beneficial effects of this utility model are:
[0012] In use, the pull rope is pressed to the oil-water boundary by the pressure wire assembly, and the second power assembly pulls the oil-repellent and water-repellent cloth by the pull rope. The oil-repellent and water-repellent cloth separates the oil and water that have been separated, so that the oil on top can be retrieved later. After the processing is completed, when the oil-repellent and water-repellent cloth is recycled, the scraping assembly scrapes off the small amount of oil and water adsorbed on the oil-repellent and water-repellent cloth.

[0021] As shown in the figure, the first power assembly includes a first servo motor 4 fixedly connected to one side of the first rotating seat 2. The output end of the first servo motor 4 passes through the first rotating seat 2 and is fixedly connected to the rotating shaft inside the first rotating seat 2, and is used to provide power for the recycling of the oil-resistant and water-repellent cloth 3.
[0022] As shown in the figure, the pressure assembly includes an electric push rod 6 fixedly connected to the top of the first gantry 5. The output end of the electric push rod 6 passes through the first gantry 5 and is fixedly connected to a first roller 7, which is used to move the pull rope 9 to the oil-water separation point.
[0023] As shown in the figure, the scraping assembly includes several limiting telescopic rods 12 fixedly connected to the bottom end of the second gantry frame 10. A spring 13 is fixedly connected to the bottom end of the second gantry frame 10 and around the limiting telescopic rods 12. A second scraper 14 is fixedly connected to the output end of the limiting telescopic rods 12. A first scraper 11 is fixedly connected to the top of the separation tank 1 and below the second scraper 14. The scraper 11 is used to scrape off a small amount of oil and water on the oil-resistant and water-repellent cloth 3.
[0024] As shown in the figure, the second power assembly includes a second servo motor 17 fixedly connected to one side of the second rotating seat 16. The output end of the second servo motor 17 passes through the second rotating seat 16 and is fixedly connected to the rotating shaft inside the second rotating seat 16, and is used to provide power for retracting the pull rope 9.
[0025] As shown in the figure, a PLC controller 18 is fixedly connected to one side of the first gantry frame 5, and a control panel 19 is fixedly connected to the first gantry frame 5 below the PLC controller 18. The control panel 19 and the PLC controller 18 are electrically connected and used to control the equipment on the device.
[0026] Working principle: During use, first check the entire device for any defects. After inspection, pour the oil and water separated from the food waste into separation tank 1. The oil and water in separation tank 1 separate into layers after sedimentation. At this point, the operator uses the PLC controller 18 via control panel 19 to control the equipment on the device. After stratification, the electric push rod 6 drives the first roller 7 to move the pull rope 9 downwards. After the pull rope 9 is moved to the oil-water separation point, the second servo motor 17 is started. The second servo motor 17 drives the rotating shaft on the second rotating seat 16 to rotate. The pull rope 9 is pulled to retrieve the oil-repellent and water-repellent cloth 3. During the retrieval process, the pull rope 9 pulls the oil-repellent and water-repellent cloth 3, which moves along the path of the pull rope 9 to separate the oil and water. After separation, the oil is retrieved. After retrieval, the first servo motor 4 is started to drive the rotating shaft on the first rotating seat 2 to rotate, so as to retrieve the oil-repellent and water-repellent cloth 3. During the retrieval process, the elastic deformation of the spring 13 causes the second scraper 14 to squeeze the oil-repellent and water-repellent cloth 3, which, together with the first scraper 11, scrapes off a small amount of oil and water on the oil-repellent and water-repellent cloth 3.
